Electrical control for electromagnets

摘要

The apparatus (1) has programmable electronic control unit (9) with electrical interconnection (3) for connecting electromagnet (2). A plug connector (4) connects electric control unit (5) to auxiliary electric current control unit (14). Another plug connector (20) has contact for spacer (11) connected with current measuring unit (12) for conducting analog voltage signal proportional to electric current of electromagnet. The plug connector has contact for spacer (13) that conducts switching signal to electronic switch (10) for switching off electrical current of electromagnet. An independent claim is included for a method for operating electrical control apparatus.
